2017-07-24migration: Use JSON null instead of "" to reset parameter to defaultMarkus Armbruster
migrate-set-parameters sets migration parameters according to is arguments like this: * Present means "set the parameter to this value" * Absent means "leave the parameter unchanged" * Except for parameters tls_creds and tls_hostname, "" means "reset the parameter to its default value The first two are perfectly normal: presence of the parameter makes the command do something. The third one overloads the parameter with a second meaning. The overloading is *implicit*, i.e. it's not visible in the types. Works here, because "" is neither a valid TLS credentials ID, nor a valid host name. Pressing argument values the schema accepts, but are semantically invalid, into service to mean "reset to default" is not general, as suitable invalid values need not exist. I also find it ugly. To clean this up, we could add a separate flag argument to ask for "reset to default", or add a distinct value to @tls_creds and @tls_hostname. This commit implements the latter: add JSON null to the values of @tls_creds and @tls_hostname, deprecate "". Because we're so close to the 2.10 freeze, implement it in the stupidest way possible: have qmp_migrate_set_parameters() rewrite null to "" before anything else can see the null. The proper way to do it would be rewriting "" to null, but that requires fixing up code to work with null. Add TODO comments for that.

2017-07-24migration: Unshare MigrationParameters struct for nowMarkus Armbruster
Commit de63ab6 "migrate: Share common MigrationParameters struct" reused MigrationParameters for the arguments of migrate-set-parameters, with the following rationale: It is rather verbose, and slightly error-prone, to repeat the same set of parameters for input (migrate-set-parameters) as for output (query-migrate-parameters), where the only difference is whether the members are optional. We can just document that the optional members will always be present on output, and then share a common struct between both commands. The next patch can then reduce the amount of code needed on input. I need to unshare them to correct a design flaw in a stupid, but minimally invasive way, in the next commit. We can restore the sharing when we redo that patch in a less stupid way. Add a suitable TODO comment. Note that I revert only the sharing part of commit de63ab6, not the part that made the members of query-migrate-parameters' result optional. The schema (and thus introspection) remains inaccurate for query-migrate-parameters. If we decide not to restore the sharing, we should revert that part, too.

2017-06-28migration: add "return-path" capabilityPeter Xu
When this capability is enabled, QEMU will use the return path even for precopy migration. This is helpful at least in one case when destination failed to load the image while source quited without confirmation. With return path, source will wait for the last response from destination, and if destination fails, it'll fail the migration on source, then the guest can be run again on the source (rather than assuming to be good, then the guest will be lost after source quits). It needs to be enabled explicitly on source, otherwise disabled.

2017-06-28migration: merge enforce_config_section somewhatPeter Xu
These two parameters: - MachineState::enforce_config_section - MigrationState::send_configuration are playing similar role here. This patch merges the first one into second, then we'll have a single place to reference whether we need to send the configuration section. I didn't remove the MachineState.enforce_config_section field since when applying that machine property (in machine_set_property()) we haven't yet initialized global properties and migration object. Then, it's still not easy to pass that boolean to MigrationState at such an early time. A natural benefit for current patch is that now we kept the meaning of "enforce-config-section" since it'll still have the highest priority (that's what "enforce" mean I guess).

2017-06-28migration: let MigrationState be a qdevPeter Xu
Let the old man "MigrationState" join the object family. Direct benefit is that we can start to use all the property features derived from current QDev, like: HW_COMPAT_* bits, command line setup for migration parameters (so will never need to set them up each time using HMP/QMP, this is really, really attractive for test writters), etc. I see no reason to disallow this happen yet. So let's start from this one, to see whether it would be anything good. Now we init the MigrationState struct statically in main() to make sure it's initialized after global properties are applied, since we'll use them during creation of the object.

2017-06-19migration: Fix race of image locking between src and dstFam Zheng
Previously, dst side will immediately try to lock the write byte upon receiving QEMU_VM_EOF, but at src side, bdrv_inactivate_all() is only done after sending it. If the src host is under load, dst may fail to acquire the lock due to racing with the src unlocking it. Fix this by hoisting the bdrv_inactivate_all() operation before QEMU_VM_EOF. N.B. A further improvement could possibly be done to cleanly handover locks between src and dst, so that there is no window where a third QEMU could steal the locks and prevent src and dst from running.
